Summary: This study investigated the mode of action of a commercial Bacillus paralicheniformis FMCH001 in promoting soybean growth under well-watered and drought conditions. The results showed that FMCH001 colonizes the roots, improves root growth, and enhances nutrient absorption from the soil. Under drought stress, FMCH001 significantly improves photosynthesis rate, stomatal conductance, and transpiration rate, resulting in increased water use efficiency. Inoculated soybean plants use 22.94% less water compared to the control, without compromising biomass production.

Summary: Tree diversity plays an important role in modulating forest productivity and buffering the effects of climatic events. This study found that tree diversity can reduce the negative impact of a sudden rise in average summer temperature on tree growth, and the effect of tree mixture on growth stability depends on the combination of tree species. Given the challenges posed by temperature rise and associated drought events in the face of climate change, tree diversity should be considered in forest management plans.

Summary: The study investigates the effects of warming and rainfall reduction on the photosynthetic nutrient use efficiency (PNutUE) and water use efficiency (WUEi) in semiarid shrubs. The results show that warming significantly reduced PNutUE, while rainfall reduction did not have a significant effect. The reductions in PNutUE with warming were mainly due to non-nutritional decreases in net photosynthetic rates. The findings suggest that warming can negatively impact the ability of native plants to cope with warmer conditions, which has implications for dryland vegetation productivity and survival under climate change.

Summary: The study revealed that the abrupt alternation of drought and flood had a significant impact on rice growth, nutrient uptake, and yield formation. Under the DFAA stresses, rice showed changes in growth characteristics and nutrient use efficiency, with increased specific absorption rates of N, P, and K but decreased NUE, PUE, and KUE. The effective utilization of N was found to be a key limiting factor, and the cumulative effect of drought and flood was weakened by their interaction.

Summary: The mechanisms of morpho-physiological adaptation to different conditions of light and flooding are species-specific, with light being more responsive than flooding for the evaluated species of the genus Eugenia. Flooding frequency in subtropical riverine forests is associated with tree species occurrence, topographic gradient, and canopy opening. Flooding tolerance varies between species and is linked to successional restoration groups. Our study tested the effects of flooding and light intensity on Eugenia involucrata and Eugenia uniflora, revealing that both species are tolerant to the combination of high light and flood. However, due to differences in root hydraulic limitation and biomass accumulation capacity, E. uniflora is more recommended for restoration projects in subtropical forests. The results also highlight that light has a greater impact compared to flooding for the evaluated species.

Summary: Changes in plant metabolism due to combined water deficit, high irradiance, and high temperatures can cause damage to crops, leading to yield losses. This study aimed to investigate the potential of potassium phosphite (PP) to induce tolerance in soybean plants under water deficit and high irradiance conditions. The experiment was conducted in a controlled growth chamber, and the results showed that PP application increased photosynthetic rate and decreased lipid peroxidation and electrolyte leakage, indicating enhanced stability of cell membranes. These positive effects may be attributed to the activation of antioxidant enzymes and osmotic adjustment. Overall, PP is a promising method to alleviate the negative effects of combined water deficit and high irradiance stresses on soybean plants.

Summary: This study examined the effects of potassium fluoride (KF) on the germination of lettuce seeds and the subsequent growth of the plants. Results showed that exposure to high concentrations of KF reduced germination rate and compromised root development. Lettuce plants also exhibited reduced photosynthesis and photochemical efficiency, as well as lower chlorophyll contents and nitrogen balance indices. On the other hand, there were increases in phenolic compounds and malondialdehyde with higher KF concentrations. These findings suggest that lettuce plants can accumulate fluoride when irrigated with KF-rich water, and the investigated physiological and biochemical markers can be useful in studying contaminants in horticulture.

Summary: Given the demand for alternatives that are less harmful to human health and the environment, this study evaluated the effect of a bioherbicide based on Trichoderma koningiopsis as an alternative weed control method. The bioherbicide, in combination with different doses of the commercial herbicide glyphosate, was tested on two weed species and soybean crops. It was found that the combination effectively controlled weed growth without causing significant damage to soybean crops. The use of synthetic herbicides in conjunction with the bioherbicide shows promise in reducing herbicide doses.

Summary: Stomata play a crucial role in plant water use and response to changing environmental conditions. By using non-destructive nuclear magnetic resonance spectrometer, the study found a strong linear correlation between relative water content at 50% stomatal conductance and mean annual temperature of the species' origin climate. The research also demonstrated stomata control over water loss and increased stomatal conductance in species adapted to warmer climates. Relative water content at 50% stomatal conductance may serve as a useful trait for comparing stomatal responses to water deficit.
